• lavc/libvorbisdec : do not return empty frames.

  lavc/libvorbisdec : do not return empty frames.
  Some parts of the code have been known to react badly to
  
  empty frames ; they should not, but there is no need to
  
  take risks.
  

  • [DH] libavcodec/libvorbisdec.c

• Should a long Running video processing task to be done client side or server side

  27 avril 2021, par Ritwiz Sinha

  I was creating an application in react for uploading video and using a REST API to send that to the server and store in S3. I also wanted the simple audio version of the video for some other tasks and I am confused as to what might be the better way :

  


  

  1. Creating audio file on the fly when it is needed using node-ffmpeg package and not store it anywhere

  


  2. Start converting the video file to audio on the browser client only, and posting that to the server for storage along with the video.

  


  3. Just post the video to the server and use queue system for creating a new task for video conversion to audio and then save that to the S3 storage.
The second method seems to be saving some compute power on the server but it might be a problem if the video upload completes, audio conversion is still going on and the client disconnects.
Would appreciate some help, thanks.

  


  


• Including FFmpeg.framework Into My IOS App

  28 mars, par Alpi

  I'm trying to manually integrate ffmpegkit.framework into my Expo Bare Workflow iOS app (built with React Native + native modules via Xcode) because the ffmpegkit will be deprecated and the binaries will be deleted.

  


  So far

  


  

  • I've downloaded the latest LTS release of FFmpegkit from here.

  


  • I've created 3 files : FFmpegModule.m , FFmpegModule.swift and SoundBud-Bridging-Header.

  


  • Added the frameworks to my projectDir/ios manually, which shows in my XCode under projectDir/Frameworks

  


  • Added all the frameworks into "Frameworks, Libraries and Embedded Content" and make them "Embed and Sign"

  


  • As Framework Search Path in Project Settings, I've set it to "$(PROJECT_DIR)" and recursive

  


  • In "Build Phases" I've added all the frameworks under "Embed Frameworks",set the destination to "Frameworks" and checked "Code Sign on Copy" to all of them and unchecked "Copy Only When Installing"

  


  • Also under "Link Binary With Libraries" I've added all the frameworks and marked them "Required"

  


  


  Here are the errors I'm getting :

  


  

  • The framework is not recognized by Swift (No such module 'ffmpegkit')

  


  • A build cycle error : Cycle inside SoundBud ; building could produce unreliable results.
Target 'SoundBud' has copy command from '.../Frameworks/ffmpegkit.framework' ...

  


  


  Below you can see my swift file and the ffmpegkit module file :
Swift :

  


  import Foundation
import ffmpegkit
import React

@objc(FFmpegModule)
class FFmpegModule: NSObject, RCTBridgeModule {

static func moduleName() -> String {
return "FFmpegModule"
}

@objc
func runCommand(_ command: String, resolver resolve: @escaping RCTPromiseResolveBlock, 
rejecter reject: @escaping RCTPromiseRejectBlock) {
FFmpegKit.executeAsync(command) { session in
  let returnCode = session?.getReturnCode()
  resolve(returnCode?.getValue())
}
}

@objc
static func requiresMainQueueSetup() -> Bool {
return false
}
}


  


  and the module :

  


  framework module ffmpegkit {

header "AbstractSession.h"
header "ArchDetect.h"
header "AtomicLong.h"
header "Chapter.h"
header "FFmpegKit.h"
header "FFmpegKitConfig.h"
header "FFmpegSession.h"
header "FFmpegSessionCompleteCallback.h"
header "FFprobeKit.h"
header "FFprobeSession.h"
header "FFprobeSessionCompleteCallback.h"
header "Level.h"
header "Log.h"
header "LogCallback.h"
header "LogRedirectionStrategy.h"
header "MediaInformation.h"

header "ReturnCode.h"

  I can provide you with more info if you need it. I've been trying non stop for 7 days and it's driving me crazy. I would appreciate any help greatly
